Description
Currently ScrollView has a
scrollToBottom() method but no scrollToTop(). While this can be achieved with scrollTo(0,0) the new scrollToTop() uses FOCUS_UP to scroll to the top position in order to solve nested problems (see: https://stackoverflow.com/a/44046801/5193915)
Example:
var win = Ti.UI.createWindow({backgroundColor: '#fff'});
var view1 = Ti.UI.createView({width:20,height:20,backgroundColor:"#f00",top:0});
var view2 = Ti.UI.createView({width:20,height:20,backgroundColor:"#f0f",top:800});
var scrollView = Ti.UI.createScrollView({height:Ti.UI.FILL,width:Ti.UI.FILL});
var btn1 = Ti.UI.createButton({title:"scrollUp",top: 10,left:0});
var btn2 = Ti.UI.createButton({title:"scrollDown",bottom:10,left:0});
btn1.addEventListener("click",function(e){scrollView.scrollToTop()});
btn2.addEventListener("click",function(e){scrollView.scrollToBottom()});
win.add(scrollView);
win.add(btn1);
win.add(btn2);
scrollView.add(view1);
scrollView.add(view2);
win.open();
